I am testing out the Mango BACNet (v. 2.1.0) MSTP running against FieldServer. I got an error message when I tried to discover device objects. Please see the error message in the attachment. For BACNet IP, I can easily communicate with the FieldServer without any problem. The FieldServer works as a Modbus RTU to BACnet MSTP gateway. I can collect data by CAS BACNet Explorer through BACNet MSTP protocol.
